PATNA: The special investigation team probing the Intermediate toppers' scam on Tuesday raided the premises of Ganga Devi Mahila College in the city with a SIT source telling reporters that a man detained on Monday night said the scamsters were charging Rs5 lakh per fake Intermediate certificate.

The SIT source said, "The man revealed that the scamsters would charge Rs5 lakh from each candidate for an Intermediate certificate without taking the exam or even enrolling with any college. A police team is now in Aurangabad district following his tip-off."

Despite the raid, the SIT team failed to nab Bihar School Examination Board (BSEB) chairman Lalkeshwar Prasad Singh and his wife and former JD(U) MLA Usha Sinha, the co-accused who was GDMC principal.

Surprisingly, the SIT is yet to procure arrest warrants from the court against the couple even after one week of FIR in the topper scam. The SIT has also not requested the court for police remand of Bachcha Roy, director of the Vishun Roy College, and the main accused in the case. Bachcha was arrested on Saturday and jailed.

SIT found an application for scrutiny from Usha's chamber at the GDMC. "Apart from the manipulation of evaluation and examination centres, those involved in the scam used to charge a huge sum of money for scrutiny of answer sheets," said an SIT officer.

The police team during the raid on the Vaishali college received complaints from villagers that Bachcha had illegally grabbed land for the college.
